* \brief RenderContext that can be used when no render context is present.
*
* Some patterns (e.g. a test class inheriting from glu::CallLogWrapper)
* currently depend on having access to the glw::Functions already in test
* case constructor; in such situations there may not be a proper render
* context available (like in test case list dumping mode). This is a
* simple workaround for that: a empty render context with a glw::Functions
* containing just null pointers.
